The men wore black suits with a single white rose pinned to their jackets while many other guests dressed in black and purple, a source tells E! News. About 80-90 people eventually arrived at The Academy's Samuel Goldwyn Theater, where Lee and Prince's ex-wives gave heartfelt speeches.

"Seeing his two ex-wives on stage was a really moving moment," the source says.

Janelle Monae and Esperanza Spalding performed throughout the evening, as well as members of The Revolution. Each musician performed Prince's songs to pay tribute to him. The source also tells us that several "moving and telling" video presentations played during the ceremony, including when Prince won an Oscar for "Purple Rain."

It wasn't a somber affair; in fact, attendees celebrated Prince's life in a happy way. "I don't want to say funeral, but it felt like what you would expect what the funeral would have been like; that's what it felt like to me," one attendee told E! News.

"It was very beautiful," another added. Prince would've appreciated it."

Cat Glover, a choreographer and singer who worked with Prince, opened up exclusively about the "emotional" event. "Tonight is so beautiful to see all these great celebrities and speakers and professors and musicians come together. And they're so humble," she shared. "And what they did tonight was amazing. As a matter of fact that's why I'm out here cause I was crying. It's just too emotional. Everything was so beautiful."

Glover also said people inside the event experienced a whirlwind of emotions. "Happy, heavenly, beautiful, somber. It is a celebration," she explained. "Although people may cry, we cry and we laugh but, yeah. It's a celebration."

The serviced ended around 10:30 pm PT, when guests were spotted saying their goodbyes and hugging.

"He would laugh, knowing his personality. He would laugh because he had a great personality," Glover said when asked how Prince would feel about the memorial service. "He would just giggle. He'd love it."
